# Local development
For the development environment you need to install these tools:
- .NET Core 3.1 SDK (opens new window)
- Docker: Windows (opens new window) | Mac OS (opens new window) | Linux (opens new window)
To execute tests and run the project for debugging, you need to run a number of dependencies.
We wrapped all our dependencies in a docker-compose file that you can use to bootstrap the development environment: The file BTCPayServer.Tests/docker-compose.yml (opens new window) can be used to spin everything up:
git clone https://github.com/btcpayserver/btcpayserver.git cd btcpayserver/BTCPayServer.Tests docker-compose up dev
# Which IDE?
We recommend using Visual Studio Code (cross platform) or Visual Studio 2019 (Windows Only) or Rider (cross platform). You can of course use VIM if you are hardcore, .NET Core is command-line environment friendly.
Visual Studio Code, Visual Studio and Rider will run the launch profile
This will run a BTCPay Server instance connecting to the services in your Docker service, so you can easily debug and step through the code.
# Build configuration
A build configuration defines how to build BTCPay Server. For example, whether to include some source files, whether to optimize for debugging or performance.
There are several build configurations:
How to use a different one during your local development depends on your IDE.
Debug is used, this is a Bitcoin only build excluding any altcoin dependencies. How to use a different one during your local development depends on your IDE.
You can select which build to use via the
-c switch in
dotnet command line. If you use command line and want to run a Release build:
dotnet run -c Release
# Launch profiles
When you start BTCPay Server locally for local development, it needs the right parameter so it can connect to the development time dependencies in the docker-compose file.
Those parameters are wrapped into the dotnet concept of
The launch profiles are specified in the launchSettings.json (opens new window).
There are currently three launch profiles:
Bitcoin is used. How to use a different one during your local development depends on your IDE.
If you use command line,
dotnet run allows you to select the launch profile of your choice:
dotnet run --launch-profile Bitcoin
# Running tests
Running tests is functioning in the exact same way as running the development time BTCPay Server.
cd BTCPayServer.Tests dotnet test
The concept of
launch profile does not apply for tests, but the concept of build configuration does. For example, if I want to run tests on the Release build:
dotnet test -c Release
The tests are already configured to use the development time dependencies in the docker-compose presented earlier.
You can use the
--f (filter) switch to run a specific test.
If you use an IDE, consult your IDE documentation to run tests or switch to different configurations.
# Altcoin support development
By default, your IDE or simple
dotnet run will use
Bitcoin launch profile on
- This means that BTCPay Server will be hosted on a local HTTP port, building without altcoin support,
- Run BTCPay Server to connect to Bitcoin only dependencies specified in BTCPayServer.Tests/docker-compose.yml (opens new window).
If you want to develop with altcoins support you need to use the
Altcoins-HTTPS launch profile, on the
Altcoins-Debug build, and run the BTCPayServer.Tests/docker-compose.altcoins.yml (opens new window).
If using command line:
cd BTCPayServer.Tests docker-compose -f docker-compose.altcoins.yml up dev cd ../BTCPayServer dotnet run -c Altcoins-Debug --launch-profile Altcoins-HTTPS
cd BTCPayServer.Tests dotnet test -c Altcoins-Debug
# HTTPS support for local development
Some browser security features may require that you use HTTPS to be properly tested.
In this case, use
Altcoin-HTTPS) launch profile. This will create a self signed certificate for your development purpose.
However, your browser will not trust it, making it difficult to debug.
You can instruct your OS to trust this development time certificate by running:
dotnet dev-certs https --trust
